test-tool: add test to verify SVPD page codes are in ascending order

[badarihp]

Per SPC specification, the Supported VPD Pages (page 0x00) INQUIRY response shall return page codes in ascending order. The existing test_inquiry_supported_vpd test verifies each listed page can be read but does not validate the ordering.

Add a new test (test_inquiry_vpd_page_codes_sorted) that sends an INQUIRY for Supported VPD Pages and asserts that each page code in the response is strictly greater than the previous one. The test properly handles error paths by routing all failures through a cleanup label.

Hi @sahlberg ,

This PR adds a new test (VPDPageCodesSorted) that verifies the Supported VPD Pages (0x00) INQUIRY response returns page codes in ascending order, as required by SPC.

The existing test_inquiry_supported_vpd validates that each listed page is readable but doesn't check ordering. This new test fills that gap.

I've verified it catches out-of-order responses correctly against a test target.

Would appreciate your review when you get a chance. Thanks!

Merged. Thanks!
